The three-year conflict between the US-backed Saudi Arabian-led coalition and Houthis, which has been aligned in Iran, has devastated Yemen and killed at least 10,000 people.
In an interview with CNN on Thursday, United Nations UN envoy to the United Nations in Yemen, Martin Griffiths, affirmed that Khashoggi's "catalysed" calls of October 2 call for peace in Yemen.
He added that the most urgent reason for American foreign policy in Yemen is the threat of hunger.
"The threat of famine is a very real threat and there is a risk that the number of people in Yemen who are at risk of dying of hunger or hunger will double, which is an urgent factor," he said.
Griffiths warned that the alternative to peace would be "devastating", leading to an increase in hunger, terrorism and other regional instability, as well as compromising the trade routes used to access Europe.
